Carotenoid-dependent plumage coloration is associated with reduced male care in passerine birds

This study shows that carotenoid-dependent plumage coloration in passerine birds is linked to reduced male care, suggesting a trade-off between sexual signaling and parental investment.

A life-history perspective on the evolutionary interplay of sex ratios and parental sex roles

This study uses evolutionary simulations to show that parental sex roles and sex ratios co-evolve, with parental care often biased toward the sex with lower mortality or faster maturation.

Breeding in an agricultural landscape: conservation actions increase nest survival in a ground-nesting bird

This study shows that conservation actions in agricultural landscapes increased nest survival and population size of Collared Pratincoles.

How do ecological and social environments reflect parental roles in birds? A comparative analysis

The paper examines how ecological and social environments influence parental roles in birds, finding that social environment, not ecological factors, affects sex differences in care provisioning.

How do biases in sex ratio and disease characteristics affect the spread of sexually transmitted infections?

This study uses mathematical modeling to show that skewed sex ratios and sex-biased disease characteristics influence STI prevalence differently in males and females.

Making the best of a bad job? Chick mortality and flexible female brood care in Snowy Plovers

This study investigates Snowy Plover female brood care decisions, finding that desertion is often a response to poor chick condition rather than a strategy for higher reproductive success.

Ecology, phylogeny, and the evolution of developmental duration in birds

This study investigates the factors influencing developmental duration in birds using phylogenetic and ecological data, finding that body size, ecology, and evolutionary history explain most of the variation.

Responses of global waterbird populations to climate change vary with latitude

This study quantifies how waterbird abundance responds to climate change across latitudes, finding declines in the tropics and increases at higher latitudes.

Phylogeny, transposable element and sex chromosome evolution of the basal lineage of birds

This study investigates sex chromosome evolution in paleognath birds, finding that tinamous have higher substitution rates and unique evolutionary strata without chromosomal inversion.

Demographic histories and genome-wide patterns of divergence in incipient species of shorebirds

This study analyzes genome-wide divergence patterns in two incipient shorebird species with gene flow, finding distinct genomic regions associated with reproductive isolation and adaptation.

Demographic causes of adult sex ratio variation and their consequences for parental cooperation

The paper examines how demographic processes affect adult sex ratio variation and its impact on parental cooperation in shorebirds.

Adult sex ratio bias in snowy plovers is driven by sex-specific early survival: implications for mating systems and population growth

The paper shows that male-biased adult sex ratio in snowy plovers is driven by sex-specific juvenile survival, not adult survival, and highlights the importance of sex-specific models for population dynamics.
